Is Justin Bieber the Latest Calvin Klein Underwear Model?!

The "Boyfriend" crooner recently shared a selfiemodeling a pair of white Calvin Klein undies. In the shot, the tattooed star lifted up his white tanktop to show off his abs and underwear in the mirror, which sparked some speculation behind the reasoning of the snapshot.

Was the Biebs hinting at a new business venture? Is he a model now? Was he participating in the same #mycalvins media campaign as Fergie, Miranda Kerr, Trey Songz and, of course, Kendall Jenner? Was he just feelin' himself and wanted to flaunt his impressive bod to his millions of fans on the social media app to see how many double taps he'd get?

Of course, the last thought seems the most convincing, however there might be more to it.

A source tells us that Bieber actually did shoot for the famous designer brand recently. E! News also reached out to the Calvin Klein rep, who says they will not comment regarding Bieber rumors. Justin's camp also had no comment.

Bieber posted yet another photo today of himself showing off his black CK underwear while hanging out by the pool. In fact, J.B. has tons of pictures on of himself on his Instagram where he's wearing a pair of CK undies (here's one, two, three other examples just for your viewing pleasure).

Last week, the brand announced that for the fall 2014 season, Calvin Klein Jeans and Calvin Klein Underwear will be brought together in one global advertising campaign featuring supermodel Lara Stone and male model Matt Terry. There was no Bieber mentioned in the release, but you know what Justin always says, "Never say never."

Do you think Bieber would make a good CK underwear model? Sound off in the comments!
